NASA’s headquarters in Washington, D.C. will be named after the first Black female engineer at the agency, Mary W. Jackson.“Mary W. Jackson was part of a group of very important women who helped NASA succeed in getting American astronauts into space. Mary never accepted the status quo, she helped break barriers and open opportunities for African Americans and women in the field of engineering and technology,” said NASA Administrator Jim Bridenstine.Bridenstine pointed out that NASA’s headquarters sits on Hidden Figures Way, which was re-named in 2019 with a bill from congress. Jackson, along with Katherine Johnson, Dorothy Vaughan, and Christine Darden, and their work in the West Area Computing Unit, were profiled in the 2016 book and subsequent movie ‘Hidden Figures.’Jackson graduated in 1942 with a dual degree in math and physical sciences, and took a job as a math teacher at first. In 1951, Jackson was recruited by the National Advisory Committee for Aeronautics, which in 1958 was succeeded by NASA. She was known as one of the ‘human computers’ at Langley. 1083

MILWAUKEE, WISCONSIN — A Milwaukee mother is livid that her 5-year-old son with autism was able to walk away from school. He was gone for about an hour and no one even knew he was missing until a stranger picked him up in a car."I can't believe my baby was out of the street and nobody had any idea that he was even missing," said the boy's mom Crystal Borzick.Her son, Blake Greenley, made it to the middle of busy Mill Road near 87th when a stranger spotted him trying to cross."His face was red," said Karen Stacy. "He was very cold. He was crying."Stacy said several cars slammed on their brakes when the boy darted across Mill Road to the median around 11 o'clock Thursday morning. She stopped and got out to try to find out what was wrong.Greenley has autism and does not usually speak to strangers. Stacy finally got him in her car and called the police. She was shocked to find no one reported him missing so she posted his picture on Facebook while she waited for officers.A friend of Borzick shared it with her on Facebook."That's the picture I got sent," said Crystal Borzick. "And as a mom, that made my stomach sink."She frantically called his school, Bruce Elementary."Nobody even has an idea that my son is missing from the school," said Borzick.Officers brought him back. When Crystal saw him she said she broke down."I cried," said Borzick. "I cried. I hugged him like I have never hugged him before. It was a relief sigh of relief, but it's also like I can't believe my baby was out of the street."She said she was told by the school her son might have left after lunch and that his regular teacher was out and a substitute was teaching.Milwaukee Public Schools gave a statement on the matter."We are grateful Blake was quickly found by a concerned community member and that he is safe. We are investigating this incident and, therefore, cannot comment further," said Andy Nelson, media manager for Milwaukee Public Schools."I have never been so scared in my life to know that anything could have happened to my child and nobody would have even known," said Borzick.She said Blake will not go to school tomorrow and she is not sure when he will return. 2198

NASHVILLE, Tenn. (WTVF) — Metro Nashville Police has released body camera video from Officer Michael Sipos, one of the six officers who helped evacuate families ahead of the Christmas morning bombing.Sipos was issued a body camera just days before the explosion.The video shows actions both before and after the blast. The explosion happens around the 3:51 mark in the video below.Officer Sipos said in a press conference on Sunday that when they arrived, they didn't really notice the RV, and parked just across from it. That was before the RV began broadcasting a message that it contained a bomb and for people to evacuate the area.You can see the RV in the video around the 1:57 mark, and hear the RV's broadcast through much of the first few minutes of the video provided by Metro police.Sipos and his fellow officers began to work at knocking on doors, evacuating families ahead of the blast. Sipos says they got in contact with about six or seven families.Sipos returned to his patrol car and was getting equipment out of the trunk when it exploded.Much of the video shows Sipos and other MNPD officers returning to Second Avenue N. heavily damaged and on fire. Officers are seen helping residents evacuate the area, many of who are dazed and unsure of what just happened. This article was written by Catlin Bogard for WTVF. 1339

Neanderthals may not have been that different from us, after all.New evidence reveals that they created the world's oldest known cave paintings and even wore seashells as body ornaments. Both behaviors suggest that they thought symbolically and had an artistic sensibility like modern humans. Two studies published Thursday in the journal Science detail the latest findings."Undoubtedly it is showing that Neanderthals were thinking and behaving just like modern humans," Alistair Pike, co-author of the studies and professor of archaeological sciences at the University of Southampton, wrote in an email."We should no longer think of them as a different species, just humans in different places," he said.The new findings of symbolic thinking show that Neanderthals and modern humans were cognitively indistinguishable, the researchers said.Cave paintings and artifacts like painted seashells have long been regarded as the work of early modern humans, who were thought to have more advanced cognitive abilities than Neanderthals. Dating cave paintings can be a difficult process, and unreliable techniques never allowed for the possibility that these could be the work of Neanderthals.Until now, that is. A new technique called Uranium-Thorium dating is less destructive, is more accurate and can go back further in time than other methods. U-Th dating looks at the deposits of carbonate on top of the paint, which contain traces of uranium and thorium that indicate when those deposits formed. That allows the researchers to determine an age for what's under the deposits.The researchers applied this technique to paintings in the La Pasiega, Maltravieso and Ardales caves in Spain, which had never received "robust" dating. The paintings include red and black images of animals, dots, lines, disks and other geometric signs. There also are engravings, hand prints and hand stencils.Those hand stencils are particularly significant, and not just because they represent the hand size of a Neanderthal."A red line, a red dot or even a positive hand print could potentially be made 'accidentally,' " wrote Dirk Hoffmann, lead author of the studies and archaeologist with the Max Planck Institute for Evolutionary Anthropology, in an email."Of course, I am sure that this is not the case, since you would still need to bring [in] light and pigment, but one could argue that all you need is some pigment on your hand when you lean against a wall. A hand stencil cannot be explained like that. You have to hold your hand against the wall and the deliberately spray pigment over this. This is why we emphasize the hand stencil."The dating revealed that the cave art was created more than 64,000 years ago -- 20,000 years before modern humans appeared in what is now considered Europe.The shells were found in the Cueva de los Aviones, a sea cave in southeastern Spain. They are unique because they are perforated with holes and colored with red and yellow pigment. Others served as containers for the mineral pigments themselves. The pigments were used on the shells but could have also been used for the cave paintings and even as body paint.The deposit layer containing the shells dated to 115,000 years ago, which is even older than other shells recovered in Africa that were dated to modern humans."The standard archaeological interpretation of such finds is that they are body ornaments," Hoffmann said. "Similar finds were made in Africa or the Levant with similar age. In Africa or the Levant, these were made by modern humans, in Spain Neanderthals made them. So in terms of symbolism, early modern humans and Neanderthals were similar."The researchers are absolutely confident in their dating technique."We have spent 10 years refining the technique and have numerous quality controls," Pike said. "The dates respect the growth axis of the deposits we are dating, the oldest closest to the painting, the youngest at the surface."Once modern humans left Africa and migrated to Europe and other areas, mixing with the Neanderthals would've been inevitable. The researchers believe that the Neanderthals created this artwork on their own, without being influenced by any other population. But it's possible that they exchanged symbolism or that Neanderthals influenced the art and symbolism of modern humans. Modern humans were capable of symbolic behavior, so it "turns the who's copying who debate on its head," Pike said."The idea that culture only evolved with modern humans no longer makes sense," Pike said. Hoffmann suggested that Neanderthals now be referred to as "very close cousins" of modern humans.Is it possible that anyone else may have created the cave paintings?Pike said it is incredibly doubtful that a population of early modern humans migrated to Europe so early without any other evidence to suggest it."We cannot of course rule out that pre-Neanderthal populations made the art," Pike said. "This sounds like a project for the future."Hoffmann, Pike and their colleagues want to use their new dating technique in more caves in Spain, as well as France and Italy -- and anywhere else Neanderthals are known to lived.The findings also raise new questions for researchers."How far back does symbolic behavior go? Can it be traced to the last common ancestor of modern humans and Neanderthals? This is perhaps where we should be looking," Pike said. 5398
